An observational study in Transthorcic Echocardiography, Stable Angina Pectoris and Coronary Artery Disease, sponsored by Tianjin Chest Hospital. Recruiting at 1 site in China. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-07-18.
Sponsored by Tianjin Chest Hospital · Observational
The investigator aims to prospectively enroll patients who were referred for transthorcic echocardiography (TTE) for the assessment of stable chest pain (SCP) suspected of obstructive coronary artery disease (CAD). All patients underwent TTE according to established guidelines and local institutional protocols. This study will determine if TTE-based imaging evaluation can provide more informaton to improve clinical management for SCP, including fewer MACE and better decision-making of downstream investigations and therapeutic interventions.
Patients who were referred for TTE for the assessment of SCP suspected of CAD.
Exclusion Criteria:
